Don't "see" it, literally, in Direct Access you mean? I didn't mean that.
I meant that it seems to be a default "hidden" OpenFilePath internally. (And since I started using it, which isn't long ago.
I don't really like it. Especially that files there don't count as "in the sandbox" when using Start/Run Access (for me: *.exe or *.*). Put something there and it can be started... In my case, I'll just assume SRP isn't bypassed and processes running without admin privs can't run anything from there anyway.
(Even though I'm using XP as admin, I'm using a little trick with registry permissions to get 2 sets of SRP rules; everything allowed as true admin.)
I already don't like how Sandboxie allows otherwise protected files (in Windows and Program Files) to be modified in the sandbox, therefore weakening things a bit from inside a sandbox. Start/Run Access doesn't solve anything for DLLs...
